Magnetic Pickup Sensors MPU
MPU Speed Sensors for Marine & Industrial Applications
AUTOMATOS KOSMOS 4U supplies magnetic pickup speed sensors, cables, connectors and technical support for main engines, generating sets and industrial equipment.
We combine sensor selection with signal verification and compatibility checks, supporting RPM measurement, governor feedback and engine monitoring applications.
⚓ Speed Measurement through Magnetic Induction
Passive magnetic pickup sensors generate an AC signal as the teeth of a ferrous gear or flywheel pass the sensing tip. No external power supply is required for the sensor itself.
Signal frequency corresponds to the tooth-passing rate and is used to calculate rotational speed. Signal amplitude depends on speed, installation air gap, gear geometry and sensor design.
✅ Main and auxiliary engine speed measurement.
✅ Speed feedback for compatible governor systems.
✅ Generating set and automation applications.
✅ Integration with compatible RPM indicators and monitoring modules.
⚓ Sensor & Connection Options
The range offers different configurations to suit installation requirements:
✅ Thread families covering 1/4, 3/8, 5/8 and 3/4 UNF, plus M12, M16 and M18.
✅ Different insertion lengths, depending on the model.
✅ Flying-lead, cable, terminal and MS/MIL connector configurations.
✅ Stainless steel or aluminium housings, depending on the version.
✅ Options for demanding operating environments, subject to the selected model’s specifications.
The technical overview lists an operating temperature range of -60 to +107 °C and a signal frequency range of 10 Hz to 12 kHz. Suitability, electrical characteristics and connection requirements must be confirmed for the specific sensor part number.
⚓ Cables, Connectors & Accessories
✅ Mounting locknuts and compatible mating connectors.
✅ Heavy-duty cables in different lengths.
✅ Custom cable lengths and connector arrangements.
✅ Five-output pulse distributor for 12 or 24 V system applications.
⚓ Technical Support & Replacement
We identify existing sensors, select suitable replacements and investigate speed measurement faults.
✅ Signal frequency, amplitude and stability measurements.
✅ Installation and air-gap checks against equipment instructions.
✅ Wiring, shielding and connector inspection.
✅ Diagnosis of unstable RPM indications or signal loss.
✅ Compatibility checks with governors, indicators and input modules.
For sensor selection, send us the existing part number, photographs, thread and insertion dimensions, connection type and details of the receiving system.
